Number and what kind spark plug for a Briggs & Stratton 6.50 engine?

A vehicle's engine cranks when the starter turns the engine crankshaft. A vehicle's engine "turns over" when the engine internal resistance is overcome by the starter turning the crankshaft. Then, you must have fuel pressure, volume, and fuel delivery.

Then the engine must be timed by its internal parts. A Spark would be nice, at that time. Fuel pressure, volume, delivery may be dependent upon spark being enabled and happenning.

The cylinders must have adequate compression. Retrace your previous work since your attempts resulted in greater loss of operation. Passing the pump and sender assembly into the tank has caused hose disconnection or a disturbed wire for technician and harry homeowner alike.

Using the complete unit from carter has been the best cheapest lucky replacement.(9H307 base number for whole unit.) Do the basics, verify and run tests/ inpection for spark, fuel, compression, and timing. In that order, first. Basic electrical, connections, protections, relays.

Run codes and test, or enter testing in the service manual strictly by symptom. Update your question. You can tell us what engine and trans you have then, how many tanks, and if its a 4x4.

You will find on any ford pickup these facts are very important. Also wheelbase and or specific build date make a difference for fuel system parts in use. Not using Ford parts opens another interesting chapter into running one without a carter fuel pump.

Libraries and the Ford garage can be a help. Auto databases contain info about specs, and service bulletins as well as recalls. Online sources contain info and discussions by other owners of the same or similar vehicles and people replacing hundreds of dollars worth of parts without a proper diagnosis.

Don't get in that mess. Sometime just the connector fitment can cause intermittent operation. Other times, parts you disturb during your attempts can be a new cause after a guess part.

Testing with the right equipment as you attempt, and having a good source for procedure, specs, and results gets you through, but only with experience. Otherwise its luck. Prayer can help but it won't fix a car or truck.

You may require a technicians help and a rental car. Depends what you do. A proper fuel testing gauge can be found at a parts or tool store, as well as a DVOM and a 12v test light.

A spark checking tool is also inexpensive. Once you find the missing need or that need present out of spec, you can be in the area where testing is required. A no start following a fuel part replacement can also have introduced air that can be purged at the injector fuel rail service port.

If you need a code checker they may lend it at the parts store. They can suggest lots of things to buy. A tester for injector pulse is also inexpensive now.

Just as a wrench and wire brush are for the battery connections. See why a shop has a basic fee for the right answer based on their time, tools,books,knowledge, people? Not to mention the laws they must obey and those costs?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
